IRONING MACHINE.

Application filed August 2,

. ToalZZ whom it may concern: I

Be it known that I, Josnrn: A. LUYBEN, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Ironing Machines, of which the following is a specification.

The invention relates to ironing machines and its object is to provide a simple and economical device which shall be highly effioient in operation.

The invention consists in a fixed shoe containing the heating element and a revoluble roller resiliently supported and bodily movable toward and from the shoe.-

In the accompanying drawings I have illustrated an embodiment of the invention in which Figure 1 is a front elevational view ofdevice constructed in accordance withthe invention; Fig. 2 an end elevational view ofthe same; Fig. 3 an elevation'alview of the opposite end of the same; Fig. 4 a crosssectional view in enlarged scale on line 4-4 of Fig.1; Fig. 5-alongitudinal crosssectional view in enlarged scale of the roller; Fig. 6 a plan view of the treadlemechanism, and-Fig. 7 a detaileview ofone of the FBCIP. rocable rods illustrating the upper connection to the bearing and the lower connection to: the operating lever.

Referring to the drawings the frame comprises end upright members 10 and 11 and cross membersor rods 12 enclosed by sleeves 13, nuts 14 securing the end members and rods together and theisleeves properly spacing the end members. A suitable support or shelf 15 issecured to end member 10 and supports electric motor 16, the shaft 17 of which is secured to a worm 18. Wormwheel 19 mounted. on shaft 20 supported by end member 10 meshes with worm 18. A pinion 21 on shaft 20 or carried by wheel 19 meshes with gear 22 mounted on shaft 23supported by end member 10. A sprocket 24 carried by gear 22.is engaged by sprocket chain 25. Chain 25 passes over two idler sprockets 26 and 27, and over sprocket 28 secured to shaft 29 carrying the roller 30. The teeth of sprockets 26 and 27 are sufficiently cut back to permit the chain to accommodate the vertical movement of sprocket 28 as the roller is raised and lowered as hereafter explained.

Shaft 29 of roller 30 is carried in two bearings 31 and 32 so mounted in end members 10 and 11 respectively as to be bodily movable in a vertical direction in the frame.

1920. Serial No. 400,881.

Suitable springs 33 engage at their lower ends the top side of each bearing and tension is placed on the same by a block car-- ried by adjusting screw 34. Shaft 29 extends exteriorly of end member 1.1 of the framev and the extended portionis hollow and enlarged as shown in Figs. 4 and 5, to form the core of roller 30. Suitable padding 35 surrounds the core and a suitable number of layers of fabric 36 surround the padding,

the outer end ofthe fabric being brought around the endof the core and engaged between plate 37 which is part of or fixed in the core and plate 38 carried on bolt 39 threaded into plate 37.

The heating or ironing shoe 40 projects laterally from the frame and is parallel to roller 30, and spaced from the shoe a suitable distance to permit the operator to insert the article to be ironed between the roller and the shoe. In. the drawings the shoe coinprises a suitable hollow casing, the face opposing the roller beingconcave, in accordance with the curvature of the roller. A coil of electrical resistance 40 is contained within the casing and is connected to sockets 40 to which a source of electric current. is connected. Any suitable means for heat ing theshoe will suflice, the electrical heater 7 being more convenient and more uniform in its operation than most other forms of heat producing devices or materials.

The relative movement of the roller with respect to the shoe is accomplished by the following mechanism. A socket 41 (Fig. 5) is formed in the lower'face of each sliding bearing 31 and 32 and is preferably tapered. A sleeve 57 projects downwardly from the lower face of each'bearing 31 and 32 and about the socket 41. The upper end of each reciprocable rod 42, 43, is slidably engaged in thesleeves respectively, the extremity of said end being tapered to seat or engage in the socket 41. A collar 44 is secured to the rod below the lower end of the sleeve and a spring 45 coiled on the sleeve bears at its lower end on the collar and at its upper end it bears on the lowerface of the bearing 31. 32. The connection between the reciprocable rods and the bearings are therefore pivotal andresilient and permit of relative moveframe. Thelower end of rod 43 is pivotally connected to the upper arm of bell crank 48 secured to shaft 47. Link 49 is pivotally connected to the lower arm of crank 48 and to the rear arm of treadle lever 50 pivotally mounted at 51 in the frame. A lug 55 pro-- jects rearwardly from the lower end of each reciprocable rod 42 and 43 andis adapted to abut a similar lug 56 projecting rearwardly from the upper end of each crank 46 I and 48, the abutment taking place when the rods have been reciprocated upwardly to movethe roller bodily toward the shoe, and

serving to limit the rotation of shaft 47 and the movement of the roller toward the shoe.

A second treadle lever 52 is pivoted, preferably, on pivot 51. Its rear end'is adapted to engage under a laterally projecting lug 53 formed on the forward end of arm 54 projecting forwardly from the centerof bell crank 48, the latter treadle lever when depressed being adapted to elevate'arm 54 and rock crank 48 and shaft 47 rearwardly, thereby causing rods 42 and 43fto recipro cate downwardly and permit roller 30 to drop by gravity to normal position- InFigs 1 and 3 the roller is in its upward or operating position with respect to the shoe. Pedal 50 has been depressed to rock shaft 47 forwardly or tothe left, Fig. 3", and thereby reciprocate rods 42 and 43 simultaneously upward to move the roller bodily toward the shoe. This movement of the shaft causes the upper arm of bell crank 48 to move forwardly or to the left, Fig; 3, arm 540i the crank moving downwardly to cause lug 53 thereon to' engage the rear end of treadle lever 52. The foot of the Opera latter lever.

carrying arm 54 with it and bell crank 48.

tor .is maintained on treadle lever until the ironing operation is completed where upon he removes his foot ifrom treadle50 and places it on lever 52 and depresses the The rear arm of lever 52 rises and shaft 47 are-rocked rearwardlyorto the right, Fig. 3, to release the engagement oillugs 55 and 56 and to cause rods 42 and 43"to lower and permit the rollerto dropto the opposite side of the roller. The resilient connection between the bearings and the frame and between the reciprocable rods 42 and 43 and the sliding bearings accommodate the roller to various thicknesses oi material in the. articles ironed, thereby ensuring complete and full ironing of every portion of the article as it passes through the machine.

Numerous means may be used to connect the driving mechanism to the roller and any suitable form of driving mechanism may be used, hence/I do not wish to be confined to the precise constructions and arrangement of driving mechanism and connections'shown and described. a

What I claim is: 1. In an ironing machine, a frame, a revolubl shaft, two vertically movable bearings for the shaft mounted in theframe', the

shaft being extended through both bearings and projecting laterally fromtheframe. at opposite sides, resilient means tooppose the vertical'movement of the bearings, a roller on, one end of the shaft, means having connection tothe' opposite endof the shaft for rotating the shaftand roller, two reciprocable rods pivotally engaging the bearings respectively, a rock shaft having operative connection to both said rods and a foot pedal having connection with'the rock shaft for rotating the same, and a shoe secured to the frame and projecting laterally therefrom parallel to theroller and having: means tol eat it; l

2; In an ironing machine, a frame, a revoluble shaft, two vertically movable bearings for the shaft mounted in the frame, the shaft being extended through both bear lugs and projecting laterally from opposite sides of the frame, each bearing having a recess in its lower side, resilient means to oppose the vertical movementbf the bearings,'a roller on one end of the shaft, means having connection with the opposite end of the shaft for rotating the shaft and the roller, a shoe secured to the frame and projecting laterally therefrom and parallel to the roller, two reciprocable rods adapted to engage in the recesses respectively at their upper ends, a rocking shaft-mounted in the frame and having an operative connection to each rod for reciprocating the rods simultlie shoe, a spring on each rod engagingthe associated bearing for opposing the up ward movement of the rod, meansto heat the. shoe and means to rock the rock shaft.

In witness whereof I have hereunto sub scribed my neme'this da of July,1920.
